ABSTRACT:
A cation permeable membrane containing areas of thin wall construction comprises a cation exchange polymer matrix having a reinforcement fabric embedded therein.
A two-step lamination procedure is described where holes are formed in a film of laminated polymer prior to a second lamination step.
The cation permeable membrane has utility in membrane ion exchange, reverse osmosis devices or in electrolytic cells such as chlor-alkali cells.
